Aims: The aim of this study was to improve the efficiency of surgical treatment of patients with zygomatico-orbital complex (ZOC) fractures, through the use of nickel titanium alloy (NiTi) and titanium (Ti) implants, taking into account the nature of the traumatic bone involvement in affected area. Methods: 120 patients with isolated zygomatico-orbital complex fractures were selected for the study. They were divided into three groups consisting of 40 patients each. Group I - Ti fixation devices and implants, Group II - NiTi fixation devices and implants, Group III – Ti+NiTi fixation devices and implants. The following parameters were compared: a) Number of rigid fixation points b) Duration of the surgery c) Complications d) Postoperative aesthetic appearance. Results: Clinically and radiologically satisfactory results were achieved in 111 cases. In the late postoperative period we observed no secondary bone displacement, ophthalmic disorders and infection. Conclusions: The main principle involved in the management of facial traumas, in particular ZOC fractures, is an accurate and complete restoration of the affected region. Different types of ZOC fractures may be formed depending on the impact force and degree of displacement of the bone. Damage to the maxillary sinus walls and orbital floor is a natural phenomenon seen in ZOC fractures. In cases of comminuted fractures we recommend the use of Ti micro- and mini-plates. In cases of not comminuted fractures – NiTi clamps. The use of mesh and porous NiTi implants in bone defect restoration is a simple and less traumatic method of reconstruction
